Ruby on Rails

try this 

arr = ["XX","YY","AB"," "] 

def self.custom_search(arr = [])

  query = []

  arr.each do |term|

    query += "title LIKE %#{term}%"

  end

  where(query.join(" OR ")) 

end

If you're using postgres DB

def self.custom_search(arr = [])

  query = []

  arr.each do |term|

    query += "title ILIKE %#{term}%"

  end

  where(query.join(" OR ")) 

end

Paste this method in any model and call it using like this

Post.custom_search(["XX","YY","AB"," "] )

Hi guys,

I'm looking for a way to pick up database records by comparing my string
to the database record's string.

The catch is that I have to "clean up" the database strings (not change
the record, just for the purpose of this query).

The basic query is:

Book.where("title = ?","hello")

And I have an array of substrings e.g.

["XX","YY","AB"," "]  (the last one is space)

So a record where "hellXX o" or "XX  YY  hellXX o YY   " would be picked
up.

Any ideas? (performance is not important)

Thanks..!
